ἀκρίς, (ίδος, ἡ (from Homer down), a locust, particularly that species which especially infests oriental countries, stripping fields and trees. Numberless swarms of them almost every spring are carried by the wind from Arabia into Palestine, and having devastated that country migrate to regions farther north, until they perish by falling into the sea. The Orientals are accustomed to feed upon locusts, either raw or roasted and seasoned with salt (or prepared in other ways), and the Israelites also (according to Leviticus 11:22) were permitted to eat them; (cf. Winers RWB under the word Heuschrecken; Furrer in Schenkel iii., p. 78f; (BB. DD., under the word; Tristram, Nat. Hist. of the Bible, p. 313ff)): Matthew 3:4; Mark 1:6. A marvelous and infernal kind of locusts is described in Revelation 9:3, 7, cf. Revelation 9:2, 5f, 8-12; see Dusterdieck at the passage.
